FAUCET.

SPECIFICATION forming part of Letters Patent No. 767,849, dated August 16, 1904. Application filed April 1, 1904. S l NO- 201,152. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. STILLMAN, a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Faucets, of which the followingis a specification.

My invention relates to water-faucets adapted for set-bowls and sinks of that class of faucets having a push-plug to operate in opening the valve; and the object of my invention is to simplify the structure pertaining to the valve proper.

The invention consists in the combination and arrangement of parts, as herelnafter described,and specifically set forth in the claims.

In the accompanying drawings, Figure 1 represents a central sectional view of afaucet or basin-cock adapted foraset-bowl and illustrating the normal position of the parts embodying my improvements as when the supply is shut off. Fig. 2 is a partial sectional view of the faucet, showing the position the operating parts assume as when-the supply is in force. Fig. 8 is a sectional view taken on line X X of Fig. 2, showing the casing for the valve-operating parts. Fig. l is a view, partly in section and partly in elevation, of a faucet or sink-cock having my improved valve structure applied therein. 1

Like letters of reference indicate like parts.

Referring to Fig. 1, A is the body or shell of the faucet, having a partition 6, which divides the supply-chamber 0 of the faucet from its discharge-chamber d. The partition I; is provided with a screw-threaded opening to receive the threaded end of a tubular casing B, and said casing is firmly secured in place in the faucet and of a length to extend'above the discharge-chamber therein. The lower end of the casing B is made solid, as at e, and which portion has at its upper face an integral annular flange f, which surrounds a vertical opening 9, communicating with another opening, 9, that enters the discharge-chamber cl of the faucet-shellA. The casing B is further provided with two series of perforations it h, extending vertically throughout its solid portion a, and each series of perforations is formed near to the opening g thereof, as shown in Figs. 1, 2, and 3.

The upper end of the casing B has an interior-screw-threaded portion to receive ascrewplug 2', which has an enlarged annular flange a" of a diameter equal to the exterior diameter of the casing B. A packing-ring is interposed between the upper end of the casing B and flange of the plug 1). The plug 2' is provided with a centrally-circular opening, one part of which is formed conical, as at Z4, whose larger end extends from the bottom face of said plug and terminates near the middle portion therein with a straight concentric opening, as shown.

The conical part of the opening 7c of the plug forms a seat for an auxiliary valve Z, said valve having an enlarged central portion exposing a conical surface to contact with the seat It and a concentric circular stem of a length to project from the top face of the said plug. The lower end of the conical portion of the valve Z is reduced in diameter, so as to form a shoulder for the end of a coil pushspring on to bear against. Said spring 122 is interposed between the auxiliary valve Z and a piston or main valve 0'.

The main valve 0 is loosely mounted in the casing B and has a recess formed in its bottom face to receive a flexible disk 2), which is secured in place by a screw r.

The faucet-shell A is screw-threaded at its upper portion to receive the threaded end of a tubular cap A, whose interior diameter is greater than that of the exterior diameter of the casing B, so as to provide a clearance which forms a water-passage s. The cap A is provided with a central vertical opening to receive the stem 6 of a knob t, which forms a push-plug to contact with the projecting end of the auxiliary valve Z. A packing-ring o is interposed between the cap A and the faucetshell A. Another packing-ring, o, is mounted on the top face of the cap A and surrounds the stem t of the push-plug, said ring being held in place by a gland-nut 10, which is screwthreaded upon its interior surface to engage the threaded end of said cap.

hen the faucet or basin-cock is closed, the parts which comprise the valve structure assumo the position shown in Fig. l that is to say, the water-pressure from the supply has passed through the perforations 7), h, thence between the peripheral surfaces of the main valve 0 and easing B, thence into the chamber a, where the pressure is maintained until acted upon to discharge. The water-pressure being in the chamber 00 of the casing forces the main valve 0 and auxiliary valve Z upon their respective seats and causes the supply to be shut off. The vent or opening 7m in the plug /1 having a much smaller area than that of the area of the supply-chamber in easily permits of pressing down the push-plug t to force the auxiliary valve Z from its seat, and simultaneously with this movement the water-pressure from the inlet or supply 0 will release the main valve 0 from its seat to the position of parts shown in Fig. 2. The main flow of pressure thence passes from the perforations /a 7L, thence through the openings 9 and g of the casing, and out through the discharge (Z in the arrow direction indicated in said figure. The clearance s is made between the casing B and the cap A of the faucet-shell for the purpose to allow the lesser pressure in the chamber a: when the faucet is open to pass through the vent or opening 7v, thence into the chamber d, and finally pass down through the said clearance 8 into the discharge a. WVhen the knob 25' of the push-plug is released to close the faucet, the spring m immediately acts to carry the auxiliary valve Z upon its seat, after which the pressure, being now confined within the chamber 00, causes the main valve 0 to bear upon its seat, and thus shut off the supply.

In Fig. 4 I show the casing which contains my valve structure as mounted in the partition of the body or shell of an ordinary sinkcock.

By my construction and arrangement of parts I form a valvestructure for faucets that is simple, durable, and inexpensive to manufacture and at the same time a valve structure having the advantage of taking the pressure from beneath the main valve to automatically close off the supply.

What I claim, and desire to secure by Letters Patent, is

1. In a faucet, the combination, with the shell having a partition dividing the supplychamber from the discharge-chamber therein, and a push-plug movable in the shell; of a valve structure, comprising a tubular casing one end of which is made solid and provided With a series of perforations or ports extending longitudinally of the casing and also provided with an opening which forms an exhaust extending from the chamber of the easing and transversely through its solid end; a main valve loosely mounted in the chamber of said casing, and having a flexible disk secured thereto and arranged to close the exhaust therein; a screw-plug secured in the opposite end of said casing and provided with a conical opening which forms a valve-seat; an auxiliary valve having a cone-shaped portion to rest on the seat of said plug and an integral stem projecting from the same; and a coil pushspring interposed between both said valves,

' substantially as set forth.

2. In a faucet, the combination, with the shell having a partition dividing the supplychamber from the discharge-chamber therein and a push-plug movable in the shell, a valve structure, comprising a tubular casing having a solid end rigidly secured in the partition of the shell, said casing having its solid end provided with perforations extending from its chamber and entering the supply-chamber of the shell and also provided with an opening extending from its chamber and entering the discharge-chamber of the shell; a pistonvalve loosely mounted in said casing and having a flexible disk to close the opening in its solid end; a screw-plug secured in the opposite end of said casing and provided with a conical opening; an auxiliary valve mounted in the opening of said screw-plug and having an integral stem to contact with the pushplug; and a push-spring interposed between said auxiliary valve and. said piston-valve, substantially as set forth.

3. In a faucet, the combination, with the shell having a partition dividing the supplychamber from its discharge-chamber and a push-plug movably mounted in the shell and entering its discharge-chamber; of a valve structure, comprising a tubular casing having a solid end arranged to rigidly secure in the partition of the shell, said casing having its solid end provided with perforations extending from its chamber to the supply-chamber of the shell and also provided with an opening or exhaust extending from its chamber and entering the discharge-chamber of the shell; a main valve loosely mounted in the chamber of said casing and having a flexible disk to close the exhaust-opening in the same; a screw-plug secured in the opposite end of said casing and provided With a conical opening; an auxiliary valve mounted in the opening of said screw-plug and having a concentric integral stem to contact with the end of the push-plug; and a coil push-spring interposed between said auxiliary valve and said main valve, substantially as set forth.

4:. In a faucet, the combination, with the shell having a partition dividing the supplychamber from the discharge-chamber therein, said partition provided with a screw-threaded opening, and a push-plug movably mounted in the shell and entering its discharge-chamber; of a tubular casing having one end solid and provided with an exterior screw-threaded surface to rigidly secure in the threaded opening of the partition, said casing extending in and having a lesser diameter than the interior diameter of the discharge-chamber and provided in its solid end with a series of perfora- IIO tions constituting the sole inlet and also providcd in its solid end with an opening forming the outlet extending from its chamber and communicating with the discharge-chamber; a main valve loosely mounted in said casing and having a flexible disk arranged to close olf the supply; a screw-plug secured at the opposite end of said casing and provided with a conical vent forming a valve-seat; and
